Performance Requirements for Rapid Test Methods. This abstract is a brief summary of the referenced standard.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Astj 1 de It c1114 the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Standard A by the mass fraction of Standard A in each of the other standards that is, 0. Last previous edition approved in as C — In such cases, only the requirement for differences between duplicates shall apply.
CO 2 Determinations in Hydraulic Cements.
This standard is issued under the fixed designation C; the number immediately following the designation indicates the year of original adoption or, in astn case of revision, the year of last revision. NOTE 3—It is not intended that the use of reference test methods be confined to referee analysis. Sodium and Potassium Oxides. Current edition approved April 15, If either of the two requirements listed above are not met, identify and correct any problems or errors found in the procedure.
Active view current version of standard. Link to Active This link will always route to the current Active version of the standard. Any test methods of demonstrated acceptable precision and bias may be used for analysis of hydraulic cements, including analyses for referee and certification purposes, as explained in Section 4.
These reagents shall include purity agents, water, repackaged reagents, concentrated acids and ammonium hydroxide, nonstandardized solutions, and indicator solutions. No other units of measurement are included in this standard. The analyst is considered qualified when the difference between the duplicate results does not vary by more than the value listed in Column 2 of Table 1 and the average of the two samples agrees with the certificate value of the CRM within the limits listed in Column 3 of Table 1 after awtm for minor components when needed.
Alternative test methods and procedures include determination of calcium oxide, calcium dioxide, magnesium oxide, loss on ignition, titanium dioxide, phosphorus pentoxide, manganic oxide, and free calcium oxide. The requirements for qualification of a test method and analyst are summarized in Table aetm. When reporting the results of referee analyses, specify which test methods were used.
The reference cement is acceptable if its assigned value agrees with the average referee value within the limits given cc114 column 3 of Table 1. Prepare three standards, each in duplicate: Longer, more complex procedures, in some instances, have been retained as alternative test methods to permit comparison of results by different procedures or for use when unusual materials are being examined, where unusual interferences may be suspected, or when unusual preparation for analysis is required.
ASTM C114 – 15 – Chemical Analysis of Hydraulic Cement
When Rapid Methods are used, qualification testing of both the analyst and the test method are required as described in 5. Such demonstration may be made concurrently with analysis of the cement being tested.
A cement shall not be rejected f114 failure to conform to chemical requirements unless all determinations of constituents involved and all necessary separations prior to the determination of any one constituent are made entirely by these methods. Active view current version of standard. When a blank determination See Note 1 i s specified, one shall be made with each individual analysis or with each group of two or more samples analyzed on the same day for a given analyte.
Reference aztm methods and procedures include determination of insoluble residue, silicon dioxide, ammonium hydroxide group, ferric oxide, phosphorus pentoxide, titanium dioxide, zinc oxide, aluminum oxide, calcium oxide, magnesium oxide, sulfur, loss on ignition, sodium and potassium oxides, manganic c1114, chloride, chloroform-soluble organic substances.
Originally approved in Requalification of the analyst is required every two years. Active view current version of standard. Recommended Order for Reporting Analyses. The alternative test methods aastm provide individual determination of specific components and may be used alone or as alternates and determinations within the basic scheme at the option of the analyst and as indicated in the individual method.
For the purpose of comparing analyses and calculating the average of acceptable results, the percentages shall be calculated to the nearest 0. The reference test methods are long accepted classical chemical test methods which provide a reasonably well-integrated basic scheme of analysis for hydraulic cements. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Recommended Order for Reporting Analyses. It is informational only and not an official part of the standard; the full text of the standard itself must astj referred to for its use and application.
A superscript epsilon indicates an editorial change since the last revision or c141. The reference test methods are long accepted classical chemical test methods which provide a reasonably well-integrated basic scheme of analysis for hydraulic cements. The standardization used for qualification and for analysis of each constituent shall be determined by valid curve-fitting procedures. The alternative test methods generally provide individual determination of specific analytes c1144 may be used alone or as alternates and determinations within the basic scheme at the option of the analyst and as indicated in the individual method.
If the v114 results do not agree within the permissible variation given in Table 1, the determination shall be repeated until two or three results agree within the permissible variation. The same test methods to be used for analysis of cement being tested shall be used for analysis of the CRM cement.
ASTM C – 15 – Chemical Analysis of Hydraulic Cement –
CO 2 Determinations in Hydraulic Cements. C Interelement corrections may be used for any oxide standardization provided improved accuracy can be demonstrated when the correction is applied to all seven CRM cements. Apparatus and materials for the test method include balance, weights, glassware and laboratory containers, desiccators, filter paper, crucibles, and muffle furnace. A When seven CRM cements are required, as for demonstrating the performance of rapid test methods, at least six of the seven shall be within the prescribed limits and the seventh shall differ by no more than twice that value.
Description of Referee Analyses. A number in parentheses indicates the year of last reapproval.
Test results from alternative test methods may be used as a basis for acceptance or rejection when it is clear that a cement does or does not meet the specification requirement.
